Hi all. I am intending to order my first BMW. The forum is great for info. and I am hoping some one can help with this one.

I am intending to order the F31 in EBII with 18" wheels. Just waiting to see the xdrive option in January. I want to stick to the 18" wheels but I'm not that happy with the 400M that would be standard.

I really like the style and colour (grey ferric) of the 18" 436M wheels on the new M135i. Both cars have mixed tyres of similar dimensions

I have a notion the 436M rim would fit the F31. I read on the forum the offset for the 400M is 34.

Can anyone confirm the offset for the 400M rim and provide the offset for the 436M or advice how best I can find this info.

I would be very grateful for you help. BMW will not recommend the 436M. They cost £1600 including vat so I can't really buy to try if you know what i mean.

Very helpful thanks. The 403's are the 19" on the M Sport. Don't seem to have the 400 M star though the 397 fits the F30/31 and it confirms the offset as 34 so it looks as though the 436's are not compatible as the ET is 45/52.

Happy days. Do you know if BMW work similiar to VW. Golf update to car were WB 22 & 45 each year.

Are you referring to physical car updates? If so over the lifecycle they always make minor adjustments like slight changes to engine output, spec changes etc etc, but generally the biggest change is midway when they make midlife facelift (LCI).

For us we ignore the LCI model and just keep the car past into the next generation, hence the purchase now so early in the F31 lifecycle.
